Question

5 yrs ago a man was 5 times as old as his son .8 yrs hence the man's age will be 2 yrs less than 3 times his son's age. find their pres.ent age​

Answer 1

Answer:

let 5 yrs ago man's age was m and son age s

m = 5s

8 yrs later

m + 13 = (s +13)×3 - 2

m + 13 = 3s + 39 - 2

m -3s = 39-2-13= 24

put m=5s

5s - 3s = 24

2s = 24

s =12

m = 5s = 5×12 = 60

five yrs ago man was 60 and son 12

present age of man and son = 60+5 and 12 +5

=65 and 17 Ans
